The volvo D13 - Prevost

Base Engine
Fuel Filter
The five-micron fuel filter traps the smallest
impurities, providing clean fuel and extending
injector life.
Oil Filter
Volvo full-flow and bypass oil filters are
manufactured to have the correct balance
between flow rate and size. This ensures that
oil flow saturates the entire filter media, and
provides for extreme oil cleanliness throughout
the service interval.
Coolant Filter
The coolant filter protects the integrity of the
coolant system, the water pump and thermostat,
and their respective seals by removing impurities
and contaminates.
Camshaft damper AND Rear Drive
The Volvo engine’s reputation for its smooth,
quiet operation is not by accident. Unique to
the D13 is a camshaft damper which absorbs
camshaft torsionals induced by the ultra-high
fuel injection pressure. Additionally, as a member
of the engine gear train, the large mass of the
flywheel absorbs inputs from the other gears
for a smoother operating engine and extended
component reliability and life.
POWER CYLINDER
At the heart of the power cylinder is a stiff
connecting rod with wide journals and four-bolt
attachment for superior strength and a rifle drilled
oil passage for pressurized lubrication of the
piston pin. For maximum strength under high
temperatures, the piston is oil-cooled and utilizes
a one-piece monotherm design. The top piston
ring uses a proprietary PVD coating process,
which when mated with the plateau honed
cylinder liners provides excellent oil control and
minimizes bore wear for long engine life.
